A cloud engineer needs to deploy a new version of a web application to 100 servers. In the past, new version deployments have caused outages. Which of the following deployment types should the cloud engineer implement to prevent the outages from happening this time?
Answer(s): B
A blue-green deployment reduces the risk of outages by maintaining two separate environments:-The blue environment runs the current stable version.-The green environment hosts the new version.Once testing confirms the new version is stable, traffic is switched from blue to green without downtime. If issues arise, traffic can quickly revert to the blue environment, preventing service disruptions.
Which of the following package managers would most likely be used with Ubuntu Linux?
Answer(s): D
APT (Advanced Package Tool) is the package manager used in Ubuntu Linux and other Debian-based distributions. It manages software installation, updates, and dependencies using the .deb package format. Common commands include apt-get install, apt update, and apt upgrade.
A cloud engineer hardened the WAF for a company that operates exclusively in North America. The engineer did not make changes to any ports, and all protected applications have continued to function as expected. Which of the following configuration changes did the engineer most likely apply?
Since the company operates exclusively in North America, restricting traffic from outside the region is an effective WAF hardening measure to reduce exposure to potential attacks. This helps mitigate threats such as DDoS attacks, automated bot traffic, and unauthorized access attempts from regions where the company does not serve customers.
Which of the following refers to the idea that data should stay within certain borders or territories?
Answer(s): C
Data sovereignty refers to the concept that data must remain within specific geographic borders or territories and be subject to the laws and regulations of that region. This is often required for compliance, security, and privacy reasons, especially in industries dealing with sensitive information like finance, healthcare, and government. Regulations such as the GDPR (General Data Protection Regulation) enforce data sovereignty by mandating that personal data of EU citizens be processed within the EU.
A cloud server needs to automatically allocate more resources during sudden peak times. This allocation does not need to occur in regular intervals. Which of the following scaling approaches should be used?
Answer(s): A
Event-based scaling automatically allocates more resources in response to specific triggers, such as sudden spikes in traffic, CPU utilization, or memory consumption. Unlike scheduled scaling, which occurs at fixed times, event-driven scaling ensures that the cloud server dynamically adjusts resources only when needed, making it an efficient solution for handling unpredictable workload surges.
